IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Letters Patent No. 173,670, dated February15, 1876; application filed June 19, 1875.

. Toall whom it may concern:

Be it known that I, GEORGE T. RIDINGS,

of Monroe City, in the county of Monroe and State of Missouri, haveinvented a new and valuable Improvement in Brick-Making; and I'do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being bad to theannexed drawings,

' combination, with a guiding-frame, a hopper,

and an arched receptacle for clay, of a reciprocating follower forpressing forward the mold-boxes, as will be hereiiiafter explained.

The inventionalso consists in the combina tion of a scraper, apressure-bar, and an arched clay-receptacle with an open hopper,- and areciprocating follower, as will be here inafter explained.

In the annexed drawings, A designates the foundation or bed of myimproved brickmolding machine, and B B are two parallel guides ofsuitable. height and length, and arranged at such a distance apart as toreceive between them three united mold-boxes, indicated by the letter 0.Between these guides B B are three rails, a a a, on which themold-boxes, and also the follower D, slide. These rails or affordbearings for the ends, and also the middle, of the mold-boxes andfollower, and they are preferably faced with metal, to give themdurability. The follower D receives a rectilinear reciprocating motionfrom a crank, b, to which a sweep, E, is applied,'by which means themold-boxes U are moved beneath a hopper, F, an arched claychine.

receptacle, G, and a pressure-plate, H, and discharged from the machine.The hopper F is formed of three sides only, the rear side being omittedfor the purpose of preventing the clay from bridging, or failing to feedproperly. The front wall of the hopper is inclined, as shown in Fig. 1,and its lower end is lighter than the plane of the mold-boxes passedbeneath it, To this front wall a plate or valve, 0, is applied, which isadjustable up and 'down for the purpose of regulating the quantity ofclay which enters the arched receptacle'G. The pressure-plate H isrigidly secured to the guides B B, and lies closely upon the mold-boxes,which are forced beneath it.

After the mold-boxes leave the pressureplate H, filled with clay, theypass beneath a purpose of facilitating the removal of the molded brickstherefrom, and also diminishing their weight. together in the machinethe front wall of one box forms the rear wall of the adjacent box, as isshown in Fig. 1.

The operation of the machine is as follows: Motion is imparted to thefollower D, and a number of molds, O, are arranged in front of it. Thesemolds are moved by the follower beneath the hopper F, and there filledwith clay. The boxes thus filled are moved into the arched receptacle G,which, when it is filled with clay, will cause the boxes to be evenlyfilled and pressed, The boxes are then forced beneath the plate H, andbeneath the-scraper J, and are finally delivered upon a table, K, fromwhich they are removed and When these boxes are i emptied.
